SPECTACLE FRAME MOUNT HOLE INDICATION MARK SHEET, GUIDE SHEET FOR SPECTACLE MOUNT HOLE FORMATION, AND FORMATION OF SPECTACLE FRAME MOUNT HOLE IN RIMLESS SPECTACLE LENS USING THOSE SHEETS

摘要

PURPOSE: To accurately and clearly indicate the position of the mount hole on the surface of the spectacle lens when the mount hole for a spectacle frame is formed in the rimless spectacle lens and to prevent the lens surface from flawing even if the cutting edge of a drill slips during drilling. ;CONSTITUTION: A center mark part 3, a datum line 7, a longitudinal line 6, a metallic stopper mount hole display part 4, a bridge mount hole display part 5, etc., are displayed by printing on one surface side of a transparent sheet 1 which is made of transparent thin synthetic resin, and an adhesive is applied. Cut area parts 8a-8d are cut away when the sheet is stuck on the spectacle lens 20. The center mark part 3 and datum line 7 of the transparent sheet 1 are aligned with the optical center mark point 21 and astigmatism axis mark point 22 of the spectacle lens 22 and the transparent sheet 1 is stuck on the spectacle lens 20. In this state, the drill is pressed against the mount hole display parts 4 and 5, which are bored successively.;COPYRIGHT: (C)1993,JPO&Japio
